GlobalRAG: Enhancing Global Reasoning in Multi-hop Question Answering via Reinforcement Learning

arXiv CS.AI

ArXi:2510.20548v4 Announce Type: replace-cross Reinforcement learning has recently shown promise in improving retrieval-augmented generation (RAG). Despite these advances, its effectiveness in multi-hop question answering (QA) remains limited by two fundamental limitations: (i) global planning absence to structure multi-step reasoning, and (ii) unfaithful execution, which hinders effective query formulation and consistent use of retrieved evidence. We propose GlobalRAG, a reinforcement learning framework designed to enhance global reasoning in multi-hop QA.
